1. Squaring of A Number Whose Unit Digit Is 5

One of the vedic maths tricks that answer how to calculate fast is squaring of a number whose unit digit is 5. You can quickly compute the square of a two-digit number that ends with 5. Irrespective of the syllabus you are studying (be it CBSE or ICSE), you will certainly come across such sums. For instance, to calculate (55) ² =?

Step 1. Multiply 55 x 55 = . . 25 (end terms)

Step 2. Take 5x (5+1) = 30

So, the answer is 3025.

Now that you have understood the process, try to find the square of 75 & 95.

2. Multiply a Number By 5

One of the popular vedic maths tricks is multiplying a number by 5. Multiplying any number by 5 can be done with a simple trick that reduces the time it takes to do the calculation. To multiply an even number by 5, simply divide the number by 2 and then add a 0 to the end of the result. For example, 2464 x 5 = 24640 (2464/2 = 1232, 1232 + 0 = 12320). To multiply an odd number by 5, subtract 1 from the number, divide it by 2, and add a 5 to the end of the result. For example, 3775 x 5 = 18875 (3775 – 1 = 1874, 1874/2 = 1887, 1887 + 5 = 18875). To test your knowledge, try 1234 x 5 = 6170 and 123 x 5 = 615.

3. Subtraction From 1000, 10000, 100000

While subtractions from 1000s seem difficult, vedic mathematics tricks make it easier. To subtract a number from 100’s multiple such as 1000, 10000, etc. quickly, one could employ the Vedic Math Tricks. For example, to subtract 1000 – 573, one could subtract each figure in 573 from 9 and then subtract the last figure from 10. Step 1. 9 – 5 = 4, Step 2. 9 – 7 = 2, Step 3. 10 – 3 = 7. Thus, the answer is: (1000 – 573) = 427. Here are some practice sums for you to try using this technique: 1000 – 857, 10,000 – 1029, 10,000 – 1264, and 1000 – 336.

4. Multiplication of Any 2-digit Numbers (11 – 19)

One of the beneficial vedic maths tricks for multiplication is to multiply any two-digit number from 11 to 19 quickly and accurately, employing this Vedic Trick. After a few times of practicing, you will be able to calculate faster than a calculator. 

Follow these 4 steps:

Step 1: Add the unit digit of the smaller number to the larger number.

Step 2: Multiply the result by 10.

Step 3: Multiply the unit digits of the numbers.

Step 4: Add the two numbers.

For instance, when multiplying 13 and 15, the answer is 195:

Step 1: 15 + 3 = 18.

Step 2: 18 * 10 = 180.

Step 3: 3 * 5 = 15.

Step 4: Add 180 + 15 = 195.

5. Dividing A Large Number By 5

One of the effective vedic maths tricks is to divide a large number by 5.

To find the answer for 16951/5:

Step 1: 16951 * 2 = 33902

Step 2: Move the decimal: 3390.2 or just 3390

To find the answer for 2112/5:

Step 1: 2112 * 2 = 4224

Step 2: Move the decimal: 422.4 or just 422

To find the answer for 4731/5:

Step 1: 4731 * 2 = 9462

Step 2: Move the decimal: 946.2 or just 946

6. Multiply Any Two-digit Number By 11

One of the vedic maths tricks for fast calculation is to finish a multiplication problem in only 2 seconds. Examples such as 32 x 11 = 352, 52 x 11 = 572, and 35 x 11 = 385 demonstrate how this method works. Why not give it a go with 19*11 and 18*11 to see if you can get the same results?

7. Multiplication Of Any 3-digit Numbers

For 808 and 206, subtract the unit digit from the actual number: 

808-8=800 

206-6=200

Select any number and add the unit digit of the other number: 

808 + 6 = 814

Multiply the product of Step 2 and Step 1: 814 x 200 = 162800

The unit digits of both numbers are 8 & 6. The product of these two numbers: 8 x 6 = 48

Last step: 162800 + 48 = 162848

Therefore, 808 x 206 = 162848For 536 and 504, subtract the unit digit from the actual number: 

536-6=530

504-4=500

Select any number and add the unit digit of the other number: 

536 + 4 = 540

Multiply the product of Step 2 and Step 1: 540 x 500 = 270000

Unit digits of both numbers are 6 & 4. The product of these two numbers: 6 x 4 = 24

Last step: 270000 + 24 = 270024

Therefore, 536 x 504 = 270024

8. Find The Square Value

Calculating the square of a number using the Vedic Maths Trick is straightforward. To do so, take the following steps:

Step 1. Select a base close to the original number.

Step 2. Calculate the difference between the original number and the base.

Step 3. Add the original number and the difference.

Step 4. Multiply the result of Step 3 by the base.

Step 5. Add the square of the difference with the result of Step 4. For example, to find the square of 99:

Step 1. Choose 100 as the base.

Step 2. Difference: 99 – 100 = -1

Step 3. Add the number with the difference = 99 + (-1) = 98

Step 4. Multiply the result with the base = 98 * 100 = 9800

Step 5. Add the product of the square of the difference = 9800 + (-1)² = 9801

Therefore, (99)² = 9801.

You can also try it for (98)², (97)², (102)², (101)² to practice.

9. Multiply any large number by 12

Simply multiply the last digit of any number by 12 before doubling each digit after that and adding them together.

For instance, 13243 * 12 =

Let’s decompose it into manageable steps:

Step 1: Multiply 13243 by 12 to get ___ (Double of last digit 3).

Step 2: Take 13243 x 12 to get 16 (now multiply 4 by 8 to get 8 Plus 3 to obtain 11; 1 will carry over).

Step 3: 13243 x 12 = ___916 (Now multiply 2 by 4 to get 4 + 4 + 1 to get 9)

Step 4. 13243* 12= 8916 (Now multiply 3 by 2 to get 6, and add 6 to 2 to get 8)

Step 5. 13243 * 12= 58916 (Now multiply 1 by 2 and multiply it by 3 to get 5)

Step 6. 13243 * 12= 158916 (Now multiply 0 by 2 and add 1 to get 0+1=2)

10. Convert Kg to Pounds

10. Conversion of Kilograms to Pounds

Here’s an illustration: 112 kg to pounds conversion.

Step 1: Double the kilogram value by two (112X2)= 224

2. Multiply the preceding number by 10 

(224/10 = 22.4).

3. Add the two numbers together: 224 + 22.4 Equals 246.4 pounds.
